After going through preliminary roster selection and multi-day camps to determine who should make it through to the next round and represent their home country at the upcoming World Junior Championship in Ufa, Russia, the participating countries have released their final rosters.

All four of the Boston Bruins prospects who were chosen for their countries’ preliminary rosters have made it through and will fly out to Russia later this month.

Malcolm Subban reportedly didn’t do so well in the scrimmages Team Canada held to determine roster cuts, but consider the season he’s having with the Belleville Bulls. He has a 15-7-3 record in 26 games played, a 2.17 goals-against average and a .932 save percentage. He’s also a brick wall in the shootout and has remained perfect in that situation even through Red vs. White scrimmaging. He should definitely see some playing time in the tournament–three goalies are going along and one may take the position of emergency goalie–based on how he’s performed so far this season.

Dougie Hamilton will go to the World Juniors with Canada for the second year in a row, although his brother Freddie won’t be coming along this year like he did in 2012. Hamilton’s a great offensive defenseman–this season he has 41 points, with eight of them being goals, in 32 games. That’s coming off a 72-point season last year with the OHL Niagara IceDogs.

Anthony Camara is also headed to Russia as part of Team Canada. He has 40 points to his name so far this season with the OHL Barrie Colts and, from the reports I read about the Canada scrimmages, he also likes to play a big physical game. Camara had one of the goals in a Dec. 13 game against University of Alberta’s team that determined final selections.

These three Bruins prospects will be captained by Ryan Nugent-Hopkins.

On Team USA’s roster is the other Bruins prospect who made it to the preliminary round of roster selection, defenseman Matt Grzelcyk with the Boston University Terriers. With BU, he has 12 points in 15 games and recently got Hockey East Rookie of the Month distinctions for his good behavior and good offensive production.

There are some exhibition games before the big tournament begins. The three Canadian Bruins cubs will take on the Finnish national team on Dec. 20 in Vantaa, Finland. The U.S. team will face Sweden that same day in the same venue. Then in Helsinki on Dec. 22, Canada and the U.S. switch adversaries–Canada vs. Sweden, U.S. vs. Finland. Those are their last tune-ups before the tournament kicks off the day after Christmas.

In the U.S., NHL Network will broadcast all of Team USA’s games live. The time difference is kind of brutal–when it is 8 p.m. there, it is 9 a.m. Eastern.
